Outlined in this report is the nature and disposition of research and development (R&D) funding on the part of Federal agencies responsible for implementing changing national energy policy objectives for 1971-84. These funding data are presented in three major sections: (1) Federal role in energy R&D support (focusing on recent trends, historical perspectives, and basic research); (2) nuclear energy R&D programs; (3) and non-nuclear energy R&D programs. Introductory material, highlights of major findings (focusing on recent funding trends), and energy R&D programs in the 1983 Federal budget are also presented. The latter include programs related to: solar energy; geothermal energy; nuclear fission; magnetic fusion; electric energy and energy storage systems; biological and environmental research; supporting research; fossil energy; energy conservation; uranium enrichment; as well as Nuclear Regulatory Commission and Environmental Protection Agency programs. Among the findings reported are those indicating: (1) significant shifts in Federal R&D energy funding policy during the past 12 years, in response to events on both the national and international scenes; and (2) growth in the share of energy within the Federal R&D total from 4 percent (1971) to 12 percent (1978-79), and a marked decline to 5 percent in the 1983 budget proposal.
